GASOLENE AND OIL SEPARATOR.

Specification of Letters Patent.

Patented Jury 2s, 1914.

Application led May 4, 1914. Serial No. 836,197.

of the city of New York, in the county of Bronx and AState of New York, have invented certain new and useful Improvements in Gasolene and Oil Separators, of which theA following is a specification.

. The present invent-ion relates to an apparatus for separating gasolene, oil and the like from water, which is 'mixed therewith incleaning and lWashing motor vehicles.

In washing motor vehicles in garages, they are usually placed upon the Hoor of the garage and a stream of water directed onto them for the purpose of removing dust, dirt` etc. The water is permit-ted to flow into'the sewer, and obviously carries with it the gasolene and oil that has been removed in the process of cleaning from the motor vehicles, and so also the drippingsff that is to say the gasolene and oil that collects in drops on the floor while the vehicles are standing in the garage. It has been found lately that the gasolene so flowing into the sewer system collects inthe sewer, resulting in frequent explosions, which are dangerous for the reason that`they are apt to seriously interfere with the proper operation of the sewer system, and drive the covers of the manholes of the sewers out of place.

One of the objects of the present invention is to provide a gasolene and oil separator which is inserted into the pipe leading to the sewer, and effectively prevents the owing of the gasolene, oil and the like into the sewer system.

Another obJect of the invention is to com,- Y

bine with the separator a mechanism which catches the sand, mud, e'tc., from the water as the saaie ows through the separator into the sewer, in order to prevent a clogging of the pipe leading to the sewer.

A further object of the invention is to produce a separator of the character described that can be manufactured on a commercial scale, or in lother words one which is sov simple to construct as not to be beyond the reasonable cost of such a contrivance.

lVith these and other objects in view, which will more fully appear as the nature of the invention is better understood, the

saine consists in the combination, arrangement and construction of,l parts hereinafter fully described, pointed out in the appended claims and illustrated in the'accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the vscope of the appended claims without depart-ing from the spirit or sacrificing any of the advantages of the invent-ion.

One of the many possible embodiments of the invention Iis illustrated in the accom-- panying drawing which is a front elevation of an apparatus constructed in accordance with the lpresent invention. l

In the drawing, the nurreral 10 indicates a closed metallic receptacle, 4preferably cylindrical in shape. This receptacle may be `supported in any suitable manner. Near its top this receptacle is provided with an inlet opening 11, to which leads a supply pipe 12, into which is inserted a valve 13 of any suitable construction to control the flow rof the liquid into the receptacle. This supply pipe receptacle, for .a purpose hereinafter to be described. Below'they receptacle 10 is loca ted a container 16 of any suitable shape,- said` container being connected by a pipe 17 with the receptacle 10, the pipe 17 leading from the' bottom of the receptacle to the top of `the container. From the top of the container extends .upwardly in a vertical direction a pipe 18, that is connected in any suitable manner a substantial distance below the level of the top of the receptacle 10 with a substantially horizontally extending pipe 19 that leadsy to the sewer. The container 16 is provided with a hand-hole 20, that is normally closed by a cover 21 its purpose being .to permit the removal o *the 'solid matter that ycollects in the container. Near its top the containery 16 is rovided with a drain cock 22, through which the contents of the receptacle 10 may be. removed before the container 16 is being cleaned.

The top f the receptacle 10 is'provided with Van air-vent 23, to prevent the formation of an air-cushion in the said receptacle.

In the side of the receptacle 10 is provided a sight-opening 24, that is covered and consequently the lower level of the gasolene and the like separated therefrom may be viewed. In the side of the receptacle are also formed a plurality of outlets 26, said outlets being disposed in dili'erent horizontal planes, and connected by pipes 27 with a discharge pipe 28. In each of the pipes 27 is inserted a valve 29.

The operation of this device is as follows: The supply pipe 12 is connected with kthe eesspool of the garage and the pipe 19 with the sewer, the entire apparatus being located below the level of the floor of the garage, and forming thus a trap that seals the sewer against a return ow. Normally the valve 13 is open, the drain cock 22 and the valves 29 being closed. The device is irst given an initial charge of clean water. 'I he mixture of water, gasolene, oil and the like enters through the supply pipe 12 the receptacle 10, where its flow is substantially retarded as the mixture is delected and spread by the bell-shaped deflector 15. This delector, retarding the flow of the liquid and spreading it over substantially the entire area of the receptacle 10, serves to prevent a churning of the liquid in the receptacle, thereby permitting the gasolene, oil and the like to separate from t e water and to rest on top of the water. Any air under compression in the receptacle 10 escapes through the vent 23. The Water from which the gasolene andtheflike has been separated flows into the container 16, where sand and other solid matter settles onto the bottom. From the container 16 the water iows through the pipes 1S and 19 into the sewer. 'l` he lower level of the gasolene and the like is viewed through the sight-hole 24 in the receptacle. Whenever it is intended to discharge the gasolene from the receptacle, that valve 29 is opened below the level of which the lower gasolene level is located. In opening the said valve, the gasolene and the like run from the receptacle through the oorresponding pipe 27 into the discharge pipe below which a vessel is placed to collect the said gasolene.

With the herein desciibed construction a complete separation of the gasolene and the rates from the latter, inasmuch as the flow of the liquid in the receptacle is materially retarded and the liquid in the receptacle is not stirred up or agitated by the intlowing liquid, due to the operation of the deflector 15. f'

It is to be observed that, inasmuch as the receptacle 10 with the container 16 and the pipe 18 connected therewith forms a U- shaped passage that is inserted into the sewer system, the apparatus serves at the same time as a trap which prevents a return flow of liquid and of obnoxious gases, etc. into the garage.

`What I claim is 1. In a gasolene separator, the combination with a closed receptacle for the liquid to be treated, of a container disposed below said receptacle and communicating therewith, a supply pipe leading into said receptacle near its top provided in the longitudinal axis 4of said receptacle with a downwardly pointing bend, flow retarding and defiecting means in said receptacle below the mouth. of said bend, a discharge pipe connected with said container extending upward in parallel relation to said receptacle, said receptacle being provided with a plurality f outlets that are disposed in (litterent horizontal planes, and means for controlling independently o each other said outlets.

2. In a gasolene separator, the combination with a closed receptacle for the liquid to be treated, of a container disposed below said receptacle and communicating therewith, a supply pipe leading into said receptacle near its top provided in the longitudinal axis of said receptacle with a downwardly pointing bend, a bell-shaped deflector in said receptacle below the mouth of said bend, a discharge pipe connected with said container extending upward in parallel relation to said receptacle, said receptacle being provided with a plurality of out- 100 lets that are disposed in different horizontal. planes, and means for controlling independently of each other said outlets.

Signed at New York, in the county of New'York, and State of New York, this 105 28th day of April, A. D. 1914.
